To provide a battery replacement determination system which can suitably determine whether or not a battery needs to be replaced.SOLUTION: A battery replacement determination system 10 comprises a voltage detection part 12 and a controller 14. The voltage detection part 12 detects a voltage of a battery 4 of a vehicle 2. The controller 14 selects a representative voltage value VR from a plurality of detection voltage values VD detected by the voltage detection part 12 at a plurality of different timings in a vehicle operation period PV from start to stop of the system of the vehicle 2. The controller 14 determines whether or not the battery 4 needs to be replaced on the basis of time-variant relations each between at least two of the plurality of representative voltage values VR respectively selected in a plurality of vehicle operation periods PV.SELECTED DRAWING: Figure 1
【課題】バッテリ交換の要否を適切に判定できるバッテリ交換判定システムを提供する。【解決手段】バッテリ交換判定システム10は、電圧検出部12およびコントローラ14を備える。電圧検出部12は、車両2のバッテリ4の電圧を検出する。コントローラ14は、車両2のシステムの起動から停止までの車両動作期間PVにおいて複数の異なるタイミングで電圧検出部12により検出される複数の検出電圧値VDから、代表電圧値VRを選択する。コントローラ14は、複数の車両動作期間PVにおいてそれぞれ選択される複数の代表電圧値VRの時間的関係に基づいてバッテリ4の交換の要否を判定する。【選択図】図1
